| 20110179562 | AUXILIARY TANK FOR A FLUSH TOILET - An auxiliary tank for the flush toilet, wherein the one end of the pulling line is connected with a floating ball of the auxiliary tank, then the line is wound from a lower pulley to an upper pulley, and passed through a penetrated hole of a hollow tube, finally the other end of the line is connected with a extension arm in a main tank. When the water level in the main tank is full, the extension arm of the water refilling pipe will be hold by the pulling line which is connected with the floating ball, to limit the refilling water into the main tank from the water refilling pipe but from the auxiliary tank. In the light of above, the flush of the toilet is still able to be operated even at the time of water outage or shutting off the water valve. In addition, the water that refills into the auxiliary tank is the recycling water. | 07-28-2011 |
| 20140059755 | GREY WATER TOILET - A toilet comprising a tank configured to hold a first supply of water therein; a bowl having an inlet and an outlet, wherein the inlet is in fluid communication with the tank, such that the bowl is configured to receive the first supply of water; and a passage having a first end, a second end, and an inlet opening provided between the first end and the second end, wherein the first end is in fluid communication with the outlet of the bowl, wherein the second end is configured to be in fluid communication with a drain pipe, and wherein the passage is configured to receive a second supply of water through the inlet opening during a flush cycle. | 03-06-2014 |

| 20100306911 | FLUSHING VALVE - A flushing valve suitable for reducing water wastage from a cistern of a toilet is described. The flushing valve comprising an inlet valve, an outlet valve and a timer valve. The timer valve is mechanically connected to both the inlet valve and the outlet valve so as to control their movement between an open and a closed position such that the timer valve prevents both the inlet valve and the outlet valve from simultaneously being in their open positions. By preventing the inlet valve and the outlet valve from simultaneously being in their open positions results in the fact that the flushing valve does not allow the cistern to start to refill until after the flush process is complete. This results in a significant reduction in the volume of water passing through the cistern during each flushing cycle. | 12-09-2010 |
| 20100293706 | WATER REFILLING DEVICE FOR WATER SAVING TOILETS - A quantitative refill device is mounted on the top end of an overflow pipe in a water tank of a water saving toilet and comprises a first pipe, a second pipe and a float device. The second pipe defines a second chamber. Initially, water flows to the overflow pipe to create a water closing through a water flow passage between the second pipe and the float pipe, especially a conical passage defined between a conical surface of the second pipe and a conical portion of the float device. Meanwhile, the float device moves upward along with the rise of the water level of the second chamber to close the conical passage. By the time the conical passage is closed, the water closing is formed, and the refilled surplus water will overflow into the water tank, thus creating a quantitative water refilling effect. | 11-25-2010 |
